What current draw do you have on your 3V3 rail? Mine is around 100 mA.

You seem quite concerned with reliability, are you planning to operate
24/7 in an inaccessible place?
No, I'm always near the radio. I might leave it by leaving the room, but
that's it. I just want it to work, and not worry about it going bang

I routinely turn the power down, for bench testing 7 to 8 V is enough.
Testing is one thing, but when TXing I use 12 V.
